Hey Green,
I just went for a full fitting experience at a place called Hot Stix Golf in Phoenix
http://www.hotstixgolf.com
. They had all the toys and a lot of drivers from me to hit. My guess is that you are not insane enough to fly down there, and then spend another $400 for a fitting session. But you seem to be waffling over shaft flex. Based on my 105 swing speed, I am defineatly going to a stiff flex. And because of my very high launch angles (some as high as 19 degrees) I am going with an 8.5 degree driver. I never would have dreamed of hitting that kind of loft, but when I tested the two clubs they lent me (Cleveland Hi Bore & Nike Sumo SQ) I hit them both pretty well. Still TBA on the purchase. I read about a golf fitter in Minneapolis (in Golf Digest about 2 or 3 issues ago)that does all that stuff, so maybe a "quick" trip down there will help you find the fitting I think you really need. Good luck. I hope to make the trip to fargo this year and try to play a few course down there.
Les in Winnipeg.
